摘　　要：我们用Ｋ２ＭＯ３Ｏ１０－Ｂ２Ｏ３助熔剂生长出尺寸为３５ｍｍ的优质Ｎｄ３＋：ＧｄＡｌ３（ＢＯ３）４激光晶体，测定了偏振的吸收和发射光谱．加工出长度为４．６０ｍｍ的激光器件，用染料激光器泵浦，潘过晶体的自倍频得到１１９．５μＪ的绿色激光输出，光－光转换效率为４．３％；通过晶体的自和频得到４４５μＪ的蓝色激光输出，光－光转换效率为７．３％．The high quality crystals of GdAl_3(BO_3)_4:Nd3+ with the sizes of 35mm have been grown from K2Mo3O10-B2O3 solvent system.The a and π polarization absorption and edrission spectra of GdAl3(BO3)4:Nd3+ have been measured. A laser output of 119.5μＪ at 0.532 μm with an optical to optical efficiency of 4.3% was obtained by using self-frequency doubling technology when this crystal was pumped by dye laser. Also, a laser output of 445μJ at 436－443 nm range with an optical to optical efficiency of 7.3% was obtained by using self sum frequency method when this crystal was pumped by dye laser.
